Olivier Giroud should join the cast of mission impossible, as he embarked on the mission to take Arsenal to the last 16.

Arsenal starts most of their matches slow and this was no different, but 15 minutes before the end of the first half Giroud opened the scoring.

It looked like more misery was to be piled on for Arsenal, when Giroud looked to suffer an ankle injury, which he shook off and converted Campbell’s pass four minutes after the break.

Olympiakos committed players forward, but luck was on Arsenal’s side as they got a penalty in the 67th minute which the Frenchman duly converted for his hattrick and sent Arsenal to the knockout stage.
